Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance. Polycarbonate lenses also protect the eye from UV light.
In 2003, U.S. consumption was 856,000 tons, 72% of which used to make polycarbonate plastic and 21% going into epoxy resins. [8] In the U.S., less than 5% of the BPA produced is used in food contact applications, [9] but remains in the canned food industry and printing applications such as sales receipts.
The use of these compounds is diminishing due to restrictions on brominated flame retardants. The reaction of BPA with phosphorus oxychloride and phenol forms BADP, which is used as a liquid flame retarder in some high performance polymer blends such as polycarbonate/ABS mixtures that are used to form the casings for household electronics.

Finding microplastics in human body parts is not new: Scientists have uncovered the minuscule waste products in human blood, lungs, brains, hearts and testicles. ... the more accumulated plastic ...
Food contact material pictogram (left) on a plastic food container in Hong Kong. Food contact materials or food contacting substances (FCS) [1] [2] are materials that are intended to be in contact with food. These can be things that are quite obvious like a glass or a can for soft drinks as well as machinery in a food factory or a coffee machine.
Studies have shown that pumping milk, freezing it in plastic bags, then subsequently heating it up will increase the contamination of microplastics in the milk. [38] Similar results have been seen from heating plastic reusable food containers in a microwave, showing the release of both microplastics and nanoplastics. [39]
Polycarbonate + acrylonitrile butadiene styrene (PC + ABS): a blend of PC and ABS that creates a stronger plastic used in car interior and exterior parts, and in mobile phone bodies; Polyethylene + acrylonitrile butadiene styrene (PE + ABS): a slippery blend of PE and ABS used in low-duty dry bearings
Testing modified atmosphere in a plastic bag of carrots. Food packaging is a packaging system specifically designed for food and represents one of the most important aspects among the processes involved in the food industry, as it provides protection from chemical, biological and physical alterations.
